M10: Gout

M10.2: Drug-induced gout

Drug-induced gout is a form of arthritis that happens as a side effect of certain medications. It's characterized by sudden, severe attacks of pain, redness and swelling in the joints, often in the big toe. These symptoms generally occur in episodes or "flares." Certain drugs, such as diuretics often used to treat high blood pressure, and medications containing salicylates, may affect the levels of uric acid in the body, leading to its build up in the joints. This accumulation of uric acid can form needle-like crystals that cause inflammation and pain, leading to a gout flare. In between flares, gout may not cause symptoms, but over time, it can lead to further joint damage.
